Performing a Security Wipe and Reloading your Operating System

Often times, WhatsApp may not be able to operate correctly due to errors originating from the BlackBerry Operating System (OS). In these cases, it may help to perform a security wipe or reload the OS. We recommend that you first try a security wipe, and if that does not fix the problem, then proceed to reload the OS.

Before beginning either of these methods, you should back up all data on your phone as they will be deleted.

Open Windows Explorer and go to the following folder: C:\Program Files\Common Files\Research In Motion\AppLoader\ and open the Loader.exe file.

In Vista 64-bit computers, the file is in C:\Program Files (x86)\Common Files\Research In Motion\AppLoader.
Depending on your computer's settings, you may need to show hidden folders (under File > Options for Windows XP or Organize > Folder and Search Options in Windows Vista).

After the device configuration has been retrieved, you will be on the Device Application Selection page. You may scroll through the list to ensure all the applications you want are selected. You can also de-select any applications you don't use to save space. Click Next.

On the next page, click on the Advanced button. Ensure that both boxes (Delete all application data and Delete all currently installed applications) are checked. Click Next.

Proceed with the OS reinstall. Note that this process may take 10-30 minutes (usually ~10 minutes). Do not disconnect the device.

Once the process is complete, re-open the BlackBerry Desktop Manager.

Select Backup and Restore and open the Restore application. Select the file to restore (Backup-(Year-Month-Day).ipd) and click Open. Follow the steps to restore your device.
